Description

Technical Field

[0001] The invention relates to the technical field of laser distance measuring equipment, in particular to a high-precision laser distance measuring device. Background Art

[0002] Laser distance measuring device, that is, equipment that measures distance by laser, the most common one is laser rangefinder, which can measure the distance to the target by modulating a certain parameter of laser, and its measuring range is usually 3.5-5000 meters; when working, the laser rangefinder will emit a beam of laser to the target to be measured, and then the laser will be reflected to the laser rangefinder, and the timer will be used to calculate the time of laser emission and reception, so as to calculate the distance from the observation point to the measurement point. In actual use, multiple measurements are often performed on the same target, and then the average value is taken as the objective measurement result.

[0003] The existing laser distance measuring devices often have the following problems during use. Specifically, some small handheld laser distance measuring devices have low accuracy when in use due to factors such as hand shaking; and some large laser distance measuring devices with brackets can be fixed on the ground when in use, but the actual ground cannot be absolutely level, which results in the line between the measuring point and the laser distance measuring device being actually inclined to the horizontal plane. The greater the inclination angle, the lower the accuracy; in addition, for large laser distance measuring devices, only one point can be measured each time after being fixed. If you want to measure points in other spatial positions, you need to move the entire device to adjust the laser emission direction, which is not convenient to use. Summary of the invention

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] See attached Figure 1 The embodiment of the present invention discloses a high-precision laser distance measuring device, including a base 1 and a laser distance meter 2, and also includes a leveling mechanism 3, a clamping assembly 4, a first angle adjustment mechanism 5, and a second angle adjustment mechanism 6. The leveling mechanism 3 is installed on the base 1 so that the base 1 can be kept horizontal; the clamping assembly 4 is used to clamp and fix the laser distance meter 2; the second angle adjustment mechanism 6 is driven and connected to the clamping assembly 4, and can drive the clamping assembly 4 and the laser distance meter 2 to rotate in a vertical plane and determine the rotation angle; the first angle adjustment mechanism 5 is installed on the base 1 and is driven and connected to the second angle adjustment mechanism 6, and can drive the second angle adjustment mechanism 6, the clamping assembly 4, and the laser distance meter 2 to rotate in a horizontal plane and determine the rotation angle.

[0054] In actual use, the high-precision laser distance measuring device is moved to a specified position, and then the base 1 is adjusted to a horizontal state through the leveling mechanism 3, and then the laser distance meter 2 is started to emit light, and the laser distance meter 2 is rotated in the horizontal plane through the first angle adjustment mechanism 5 so that the light and the measuring point are located in the same vertical plane, and finally the laser distance meter 2 is rotated in the vertical plane through the second angle adjustment mechanism 6 so that the end point of the light coincides with the measuring point. At this time, the actual length of the light can be measured, and then the inclination angle between the light and the horizontal plane is determined by the rotation angle of the second angle adjustment mechanism 6. According to the sine function and cosine function in the trigonometric function, Function, the vertical distance and horizontal distance from the measuring point to the laser rangefinder 2 can be calculated to avoid the result error caused by the inclination angle; in addition, since the laser rangefinder 2 can be rotated in the horizontal plane through the first angle adjustment mechanism 5, and the laser rangefinder 2 can be rotated in the vertical plane through the second angle adjustment mechanism 6, the extension direction of the light emitted by the laser rangefinder 2 can be adjusted without moving the entire high-precision laser rangefinder device, so that the light falls on other measuring points, which is more convenient and quick to use; in general, by using the high-precision laser rangefinder device, the distance measurement is more accurate, and the distance to points at different spatial positions can be measured without moving the entire device.

[0055] It should be noted that the high-precision laser ranging device can measure the distance between the measuring point and the laser rangefinder 2. Specifically, if the two are located in the same horizontal plane, the above distance is the horizontal distance; if the two are located in different horizontal planes, the above distance is used as the hypotenuse of the right triangle. Through trigonometric functions, the vertical distance and horizontal distance from the measuring point to the laser rangefinder 2 can be calculated.

[0056] Furthermore, the distance between two measuring points can also be measured by the high-precision laser distance measuring device. Specifically, if the two measuring points are located in the same horizontal plane, the distances between the two measuring points and the laser distance measuring device 2 can be measured by the laser distance measuring device 2. The two distances are taken as two sides, and the horizontal angle between the two sides can be measured by the second angle adjustment mechanism 6. At this time, the length of the two sides of the triangle and the angle of the angle are known, and the length of the third side, that is, the distance between the two measuring points, can be calculated according to the cosine theorem. If the two measuring points are located in different horizontal planes, the horizontal plane where the laser distance measuring device 2 is located is taken as a reference, and the lengths of the vertical sides and horizontal sides of the two measuring points can be calculated respectively, and then the distance between the two measuring points can be calculated by the combination of trigonometric functions and the cosine theorem.

[0057] See attached Figure 1 and attached Figure 4 There are various ways and structures for adjusting the level, and one of them is introduced in this embodiment. Specifically, the leveling mechanism 3 includes a spirit level 31 and multiple leveling components 32. The spirit level 31 and the multiple leveling components 32 are all arranged on the base 1. The spirit level 31 is used to detect the horizontality of the base 1. The bottom of the leveling component 32 abuts the ground and is used to adjust the distance between the bottom of the base 1 and the ground.

[0058] Through the design of the above structure, the distance between each part of the bottom of the base 1 and the ground is adjusted by multiple leveling components 52, and then the level meter 51 is used to determine whether the base 1 is located in the horizontal plane. When the base 1 is located in the horizontal plane, the horizontal adjustment is completed.

[0059] It should be noted that the type, quantity and other parameters of the spirit level 31 are not limited in the present application and can be flexibly selected according to actual needs. For example, if a ruler-type spirit level is used for the spirit level 51, then one spirit level 51 can only measure whether one line is horizontal. Therefore, two spirit levels 51 can be set and their extension directions can be crossed with each other. If the two crossed lines are located in the horizontal plane, then the plane passing through the above two lines must be in a horizontal state. Furthermore, the spirit level 51 can be embedded in the base 1 to keep the surface of the base 1 flat and provide a certain degree of protection for the spirit level 51.

[0060] See attached Figure 1 , Attachment Figure 5 and attached Figure 7Based on the above scheme, in order to be able to adjust the distance between the bottom of the base 1 and the ground, the following design is carried out in this embodiment. Specifically, a plurality of first threaded holes 101 and a plurality of guide holes 102 are provided on the base 1. The number of the first threaded holes 101, the guide holes 102, and the adjustment components are the same and correspond one to one. The adjustment component includes an adjustment screw 321, a guide rod 322, and a support member 323. The adjustment bolt is engaged in the first threaded hole 101; the guide rod 322 is slidably connected in the guide hole 102; the top of the support member 323 is rotatably connected to the adjustment bolt and fixedly connected to the guide rod 322, and the bottom of the support member 323 abuts against the ground for support.

[0061] Through the design of the above structure, by rotating the adjusting screw 321, the base 1 and the support member 323 can be moved closer to or farther away from each other along the direction of the guide rod 322, so as to change the distance between a certain position at the bottom of the base 1 and the ground.

[0062] See attached Figure 1 and attached Figure 5 Furthermore, when the thickness of the base 1 is relatively thin, in order to prevent the first threaded hole 101 from being too short and causing the adjustment screw 321 to be unstable, a corresponding protrusion 8 can be provided on the base 1, and the first threaded hole 101 can be opened on the above-mentioned protrusion 8 to increase the length of the first threaded hole 101.

[0063] See attached Figure 1 and attached Figure 6 There are many structures with a clamping effect. In this embodiment, the following design is carried out. Specifically, the clamping assembly 4 includes an extension plate 41, a fixing member 42, a plurality of spring telescopic rods 43, and a moving member 44. The extension plate 41 is used to carry the laser rangefinder 2 and drive the connection to the first angle adjustment mechanism 5; the fixing member 42 is located on a vertical plane and fixedly connected to the extension plate 41; the plurality of spring telescopic rods 43 are parallel to each other and arranged horizontally, and one end of each spring telescopic rod 43 is fixedly connected to the fixing member 42; the moving member 44 is located on a vertical plane and fixedly connected to the plurality of spring telescopic rods 43 at the same time, and the laser rangefinder 2 can be clamped and fixed between the moving member 44 and the first angle adjustment mechanism 5 under the elastic force of the spring telescopic rods 43.

[0064] Through the design of the above structure, the moving part 44 is moved along the extension direction of the spring telescopic rod 43 and away from the second angle adjustment mechanism 6 by applying force to the moving part 44 by hand, so that the spring telescopic rod 43 is compressed and accumulates potential energy, and then the laser rangefinder 2 is placed on the extension plate 41 and located between the moving part 44 and the second angle adjustment mechanism 6. After that, the hand is released, and under the elastic force of the spring telescopic rod 43, the moving part 44 will approach the second angle adjustment mechanism 6 along the extension direction of the spring telescopic rod 43 and clamp the laser rangefinder 2. It has the advantages of simple structure, convenient disassembly and assembly, and reliable fixation.

[0065] It should be noted that after the laser rangefinder 2 is fixed by the above scheme, the laser rangefinder 2 itself is not at the center of the circle when it rotates horizontally, so there will be a certain error when measuring the distance between two measuring points. The closer the laser rangefinder 2 is to the center of the rotation circle, the higher the accuracy, until it coincides and reaches the highest accuracy. However, the laser rangefinder 2 usually measures a longer distance, so the above error can be ignored.

[0066] Furthermore, an anti-skid pad may be provided on the side of the moving member 44 close to the second angle adjustment mechanism 6, which can not only increase the friction force to prevent the moving member 44 and the laser rangefinder 2 from moving relative to each other but also provide a certain buffering effect.

[0067] See attached Figure 1 , Attachment Figure 2 and attached Figure 5 In order to enable the laser rangefinder 2 to rotate in the horizontal direction and determine the rotation angle, the following design is carried out in this embodiment. Specifically, a first angle scale 103 arranged in a circular array is provided on the top of the base 1. The first angle adjustment mechanism 5 includes a first rotating member 51 and a first locking assembly 52. ​​The first rotating member 51 is rotatably connected to the middle part of the base 1 and is arranged corresponding to the first angle scale 103. The first rotating member 51 is provided with a first pointer 53 corresponding to the first angle scale 103. The first rotating member 51 and the surface formed when the first rotating member 51 rotates are both located in the horizontal plane; the first locking assembly 52 is installed on the base 1 and is arranged corresponding to the first rotating member 51, and is used to lock and fix the relative position of the first rotating member 51 and the base 1 or release the lock of the first rotating member 51.

[0068] Through the design of the above structure, the laser rangefinder 2 can be rotated in the horizontal plane by rotating the first rotating member 51, and the rotation angle of the laser rangefinder 2 in the horizontal direction can be determined in conjunction with the first pointer 53 and the first angle scale 103; in addition, the relative position of the first rotating member 51 and the base 1 can be fixed by the first locking assembly 52 to prevent the laser rangefinder 2 from continuing to rotate in the horizontal plane.

[0069] See attached Figure 1 and attached Figure 2 There are many ways and structures that can play a locking and fixing role. This embodiment introduces one of them. Specifically, the side of the base 1 is provided with a second threaded hole 104 corresponding to the first rotating member 51, and the first locking assembly 52 includes a first locking bolt 521 and a first handle 522. The first locking bolt 521 is engaged in the second threaded hole 104; the first handle 522 is arranged at an end of the first locking bolt 521 away from the first rotating member 51.

[0070] With the above structural design, when the first handle 522 is rotated, the first locking bolt 521 can be rotated accordingly to approach and abut against the first rotating member 51 to lock it, or move away from and release the locking of the first rotating member 51 .

[0071] See attached Figure 1 , Attachment Figure 3 and attached Figure 5 In order to enable the laser rangefinder 2 to rotate in the vertical direction and determine the rotation angle, the following design is carried out in this embodiment. Specifically, the second angle adjustment mechanism 6 includes a connecting member 61, a second rotating member 62, and a second locking assembly 63. The connecting member 61 is vertically arranged and the bottom is fixedly connected to the middle of the first rotating member 51. The connecting member 61 is provided with a second angle scale 65 arranged in a circular array; the second rotating member 62 is rotatably connected to the connecting member 61 and is arranged corresponding to the second angle scale 65. The second rotating member 62 is provided with a second pointer 64 corresponding to the second angle scale 65. The second rotating member 62 and the surface formed when the second rotating member 62 rotate are both located in the vertical plane; the second locking assembly 63 is installed on the connecting member 61 and is arranged corresponding to the second rotating member 62, and is used to lock and fix the relative position of the second rotating member 62 and the connecting member 61 or release the lock of the second rotating member 62.

[0072] Through the design of the above structure, the laser rangefinder 2 can be rotated in the vertical plane by rotating the second rotating member 62, and the rotation angle of the laser rangefinder 2 in the vertical direction can be determined by cooperating with the second pointer 64 and the second angle scale 65; in addition, the relative position of the second rotating member 62 and the connecting member 61 can be fixed by the second locking assembly 63 to prevent the laser rangefinder 2 from continuing to rotate in the vertical plane.

[0073] It should be noted that the present application does not limit parameters such as the structure and size of the connecting member 61, and it can be flexibly rotated according to actual needs. For example, in the present embodiment, the lower part of the connecting member 61 is set to a structure similar to a cross to facilitate the rotation of the first rotating member 51, and the upper part of the connecting member 61 is set to a structure similar to a cylinder to facilitate the determination of the center position.

[0074] See attached Figure 1 and attached Figure 3 There are many ways and structures that can play a locking and fixing role. This embodiment introduces one of them. Specifically, a side surface of the connecting member 61 is provided with a third threaded hole 66 corresponding to the second rotating member 62, and the second locking assembly 63 includes a second locking bolt 631 and a second handle 632. The second locking bolt 631 is engaged in the third threaded hole 66; the second handle 632 is arranged at an end of the second locking bolt 631 away from the second rotating member 62.

[0075] Through the design of the above structure, when the second handle 632 is rotated, the second locking bolt 631 can rotate accordingly to approach and abut against the second rotating member 62 to lock it, or move away from and release the locking of the second rotating member 62 .

[0076] See attached Figure 1 and attached Figure 4 The fixed laser ranging equipment is usually large in size and inconvenient to move. In order to solve the above problem, the following design is carried out in this embodiment. Specifically, it also includes a plurality of mobile telescopic components 7. The plurality of mobile telescopic components 7 are all installed on the base 1. The high-precision laser ranging device can be moved or fixed by telescopic means. The mobile telescopic components 7 include an electric telescopic rod 71 and a plate body 72. The electric telescopic rod 71 is installed on the base 1. The bottom of the electric telescopic rod 71 is located below the base 1 and can be moved away from or close to the base by telescopic means. The top of the plate body 72 is fixedly connected to the bottom of the electric telescopic rod 71, and a plurality of pulleys 73 are provided at the bottom of the plate body 72.

[0077] Through the design of the above structure, when it is necessary to fix the high-precision laser ranging device, the electric telescopic rod 71 can be shortened to move the plate body 72 upward until the pulley 73 is suspended and the leveling group mechanism 3 is in contact with the ground. At this time, the friction between the high-precision laser ranging device and the ground is increased, and it is more stable and firm after being placed, and is not easy to be misplaced; when it is necessary to move the high-precision laser ranging device, the electric telescopic rod 71 can be extended to move the plate body 72 downward relative to the base 1 until the pulley 73 is in contact with the ground and the leveling group mechanism 3 is suspended. At this time, the friction between the high-precision laser ranging device and the ground is reduced, and the high-precision laser ranging device can be easily moved under the rolling action of the pulley 73.

[0078] Furthermore, the following design is also carried out in this embodiment. Specifically, there are two movable telescopic components 7, and two pulleys 73 are connected to the bottom of each plate body 72. The four pulleys 73 are arranged in a rectangular array, and the two pulleys 73 at the bottom of one of the plate bodies 72 are universal wheels, and the two pulleys 73 at the bottom of the other plate body 72 are directional wheels.

[0079] Through the design of the above structure, the high-precision laser distance measuring device can be made more flexible when moving and turning, more controllable, and more convenient to use.

[0080] Furthermore, a handle 9 may be provided on the base 1 to serve as a fulcrum and assist in pushing the high-precision laser distance measuring device.
